T oaZZ whom it may concern:

Be \it known that I, RUFUS T. DAVIS, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented 5 the Hanger,(Case 13,) of which the following is a specification.

One object of my invention is to provide a relatively simple, compactand inexpensive form of hanger for mounting in the ceilings, beams,girders, walls, etc., of buildings, for the support of structures suchas light fixtures, brackets, bearings, etc.,the invention moreespecially contemplating a novel device adapted to permit of theinsertion of a headed structure and its subsequent retention.

Another object of my invention is to provide a hanger or insert withretaining elements of novel form and mode of operation, for engaging andpreventing the withdrawal of a headed structure after this has beeninserted ;-the arrangement being such as to permit of a limited lateraladjustment of said headed structure.

Another object of the invention is to provide a ceiling insert or han erof the above noted general type which w iile inexpensive to construct,shall be substantial and structurally strong as well as of sucha natureas to permit of the insertion of a suitable headed member with theutmost convenience and speed of operation. 7 A t These objects and otheradvantageous ends I obtain as hereinafter set forth, reference being hadto the accompanying drawings, in which- Figure 1 is a vertical sectionof the hanger constituting my invention;

Fig. 2 is a vertical section on the line 2-2, Fig. 1;

Fig. 3 is a horizontal sectionon the line 8-3, Fig. 1; and

Fig. 4 is an inverted plan of the hanger.

In the above drawings 1 represents a hollow, somewhat elongated; metalstructure, usually though not necessarily a casting, closed at the topand open at the bottom. Its top or upper end is formed with an externalprojecting flange 2 and there is a similar outwardly projecting flange 3extending around its bottom end which preferably has a substantiallycircular outline and is formed with notches 5 for the reception of nailswhereby it may be held in 5 place upon wooden forms.

HANGER.

While .two ofthe opposite interior walls of the hanger body 1 are planeand parallel, the two other interior walls are respectively providedwith pockets 6 whose lower sides are inclined toward the open lower. endof said body. Adjacent said pockets the hanger body has outwardlyextending portions 7 internally recessed as indicated at 8, and intoeach of these recesses extends an arm 9 having mounted on its outer end(in the present instance integrally) a cylindrical structure 10 whoselength is substantially equal to the width of the main cavity of thehanger between its plane walls.

Each of the arms 9. is movably retained within its recess 8 by a pivotpin 11 which extends across the recess from side to side thereof, sothat each of the cylindrical heads 10 is free to swing into and out ofits pocket 6; the arrangement of parts being such that under normalconditions said two heads remain under the action of gravity in theirlowest positions, resting againstithe oppositely inclined faces of thepocket walls and at a minimum distance apart.

lVhen under conditions of use the hanger is mounted in place in aceiling or connected to a structure such as a girder with its open enddownward, a headed structure such as the bolt w indicated in dottedlines, maybe entered in said end and forced upwardly within the hollowof said hanger. This causes the two heads '10 to swing apart about theirpivot pins 11 as axes until they enter their pockets 6 and occupypositions such that the head of the bolt may pass between them.Thereupon both of said retaining members fall under the action ofgravity into the positions indicated in Figs. 1 and 2,.so that when thebolt w is released, it is held within the hanger since its head issupported upon the two heads 10. Obviously there is no possibility ofsuch a bolt being accidentally dislodged or pulled out of the hangersince the heads 10 cannot move apart sufficiently to permit this actionunless they should first be manually raised and moved into theirrespective pockets.

With the construction illustrated there is no possibility of theswinging members constituted by the parts 910 becoming jammed orunintentionally held in their raised positions, nor is there anythingwhich would cause them to be similarlyheld in their lower positions insuch manner as to prevent the insertion of the headed structure 00 whenthis is desirable.

I claim v 1. The combination of a hollowbody having a bottom opening andan interior in clined bearing surface leading thereto; with an armpivotally connected at one side ofthe body and having a transverselyextending cylindrical head free to move toward and from the opening,said head being positioned to swing into engagement with the bearingsurface when drawn toward the opening by a headed member extendingtherethrough.

2. The combination of a hollow body having a bottom opening and providedwith pockets on opposite sides and bearing surfaces adjacent thereto;two headed elements pivotally connected to the body and free to swinginto and out of their respective pockets to admit a headed structure,said ele-
